 # Installation on existing client
 
-An easy method to test the lmn-client is to run the playbook manual on a fresh installed client.

-## Using your own livebox server
+
+## Using your own repository and LinuxMuster.Net tftp
+
+If you fork the lmn-client repository, you can customize the preseeding and inventory to your needs.
+Use the instructions in the previous section and customize the repository in `/srv/linbo/boot/grub/lmnclient.cfg`.
+
+It makes sense to encrypt your inventory via `ansible-vault`.
+When using encrypted inventories you have to provide the vault password by commenting in the two lines in the `/srv/linbo/boot/grub/lmnclient.cfg`.
+
+## Using your own repository and livebox tftp
+
+The next improvement will be to use your own livebox with following functionalities:
+
+* Providing linux kernel and initial ramdisk for installer
+* Can be used as cache for debian packages (aptcacher)
+* Can provide mscorefonts and libdvdcss (multimedia codecs)
+* Can be used to boot live systems (netboot) via pxe
+
+### Installing the livebox server
+
+* Install debian VM and configure network
+* Install additional packages: ansible  
+  `sudo apt install ansible`
+* Run livebox playbook  
+  `ansible-pull -i localhost, --url=https://salsa.debian.org/andi/debian-lan-ansible.git -C master livebox.yml`
+* Set DNS entry for your new livebox server
+
+### Modification LinuxMuster.Net server
+
+The file `/srv/linbo/boot/grub/lmnclient.cfg` might look like this:
